Crypto-Pegmon-MCP

An MCP server that tracks stablecoin peg integrity across multiple blockchains, helping AI agents detect depegging risks before they escalate.

Features

• Stability Reports: Generate detailed reports assessing stablecoin peg stability, including maximum deviation and status (Stable, Moderately Stable, Unstable).
• Real-Time Price Monitoring: Fetch current prices and calculate peg deviation from $1 for USD-pegged stablecoins.
• Historical Data Analysis: Retrieve historical price data (up to 7 days by default) in Markdown table format.
• Supported Stablecoins: Monitor 17 USD-pegged stablecoins, such as Tether (USDT), USD Coin (USDC), Dai (DAI), and yield-bearing tokens like Ethena Staked USDe (eUSDe).
• User-Friendly Output: All data is presented in clean Markdown format for easy integration into reports or dashboards.
